The desktop website resides in an httpdocs folder, this is where I have installed the Sitemap generator.

However, the mobile version is in another folder outside the httpdocs folder called mobile. In Plesk I have set up a subdomain that forwards to this mobile folder. This subdomain is called m.mydomain.co.uk

I am not sure what route to take regarding setting up Sitemap generator:

1. Do I set up one installation and set up a mobile sitemap with an inclusion mask. If so, I assume I could only use a full path name within this inclusion mask such as:/var/www/vhosts/mydomain.co.uk/mobileEven if this can be undertaken, the main problem I foresee with this is the mobile sitemap will reside in desktop domain folder and not the mobile subdomain.

Or do I do:

2. Create two installations, one in the httpdocs folder and one in the mobile folder. If this is the correct method, then I would only want the mobile version of the sitemap in the mobile folder, so how do I stop a normal xml sitemap being created within this subdomain as well?

Obviously if there is a better method then either of these two, I am happy to undertake it.

What I don't understand is how this can be ignored. For example, if I leave checked 'Ping Search Engines on Completion' won't this then notify the Search Engines with the Normal Sitemap which has been created (which I don't want) AS WELL as the mobile version (Which I do want)?

In reply to my question above, so I can ignore the xml feed I do not need, would I add into the robots.txt file in the sub domain the relevant code that would point to the mobile xml feed, for example:
